Abstract

This study investigated the uncertainty evaluation procedure in the dynamic torque realised by a dynamic torque generating machine (DTGM) based on an electromagnetic force under development at NMIJ. The dynamic torque can be generated by changing the applied current. The generated torque can be traceable to the International System of Units (SI) by referring to the national standards of voltage, current, angle, and frequency.
